{"id":"AZL-77547","summary":"CVE-2026-2303 affecting package telegraf for versions less than 1.29.4-21","details":"The mongo-go-driver repository contains CGo bindings for GSSAPI (Kerberos) authentication on Linux and macOS. The C wrapper implementation contains a heap out-of-bounds read vulnerability due to incorrect assumptions about string termination in the GSSAPI standard. Since GSSAPI buffers are not guaranteed to be null-terminated or have extra padding, this results in reading one byte past the allocated heap buffer.","modified":"2026-04-21T04:34:17.949360Z","published":"2026-02-10T20:17:00Z","upstream":["CVE-2026-2303"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2303"}],"affected":[{"package":{"name":"telegraf","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/telegraf"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.29.4-21"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-77547.json"}}],"schema_version":"1.7.5"}
